Is there really this type of meat chicken ???

[deerman]

Hybrids will not breed true....because some will take after the cornish side, other after the white rock side, yes some will be like rock cornish. Not all

In raising terminal x bred animals, it always boils down to good management. Those that successfully raise chickens study and follow the proper protocol to raise these chickens. Those that don't , experience poor results, then they complain, badmouth, and post what amounts to untruths as millions are successfully produced every year. The CornishX is a terminal cross that produces the most amount of meat in the shortest time possible with the most efficient feed conversion rate in chickendom. They are produced and meant for the table, not reproduction. Simple as that. If someone wants to reinvent the wheel, spend millions of $$$ and years of reasearch, then start with at least 4 super selected grandparent lines to achieve a similar result. The grandparent and parent lines all breed naturally as doing AI is not economically feasible. Many are now finding out when trying to breed on the Freedom Rangers as well as other terminal cross birds... chances are they will not breed true and/ or experience similar mortalities as they mature similar to the Cornish Xs.

Lets see if we can clarify this:

Meat Birds are commonly called Cornish X's because they are based on Cornish
Game roosters and and a Rhode Island White hen. The roosters bring good feed conversion,
excess muscle size, and fast growth.
The hens bring fast growth, voracious appetite, early maturity, and good egg laying.

The results are our well known little monsters!



This doesn't need to be done with egg layers because the needed genetics are apparently
dominant and can be maintained in one line.
The chief reason is that good egg laying ability is needed in the hens for efficient feed conversion
The feed to achieve the whole process has to be accounted for.
Some of the Genes necessary for maximum meat production aren't compatible with good laying.

I suspect the basic genes aren't that difficult to combine, but the breeds have been fine tuned for
decades for every possible advantage.

A year or so ago someone reported here on BYC a Cornish X rooster that was supposed to be 24 lbs.

This guy may be an anomoly , he weighed 16 lbs , 14 oz at 6 months last fall and bigger now and still going strong ; though thats not to say he will not drop dead tomorrow . He was raised on a controlled diet , plus was always looking two weeks behind the other CX ; then he caught and passed the other two cockerals [ now dead ] last summer . He's been pretty active , and was breeding last fall but seldom getting fertile eggs and I've never succeeded at hatching one . I think he's simply too large to get in the proper position . I'm waiting to see if he lives till warmer weather and goes back to attempting to breed . His comb tips have frostbitten in the subzero temps and none of my chickens are laying well or breeding right now .

I have had some live well past 2yrs. I now have some more that are almost 1 yr that I plan on keeping!!!!!

 

[KatyTheChickenLady]

yes, it can be done! good for you

but as you know & like steve said it takes restricted diet & exercise from the beginnning

 

[Bossroo]

Steve, Come spring, try pulling out some of the longer feathers around the vents ( leave the very short ones on right on/ next to the vent)of that CornishX rooster as well as the hens. You then just might start getting fertile eggs. I did this when I raised canaries, finches, parakeets, cockateels, and pheasants with great success.

Actually the modern CX are not a cross of pure Cornish on pure White Rock or any other breed any longer . The parents of the terminal cross are crosses themselves , and look very much like , along with having many of the same problems as , the ones we buy for feeding out . They're fed restricted diets and culled after the first breeding season at around one year of age ; some of the cockerals sometimes have to be replaced during that one season to keep fertility high .

And the parent stock is heavily protected by the breeders. I've been to a couple chicken farms to work on equipment but I'm not allowed anywhere near the breeders. They are indoors and out of sight.
